Celvestrant PFS Injection is a type of medication that acts as an estrogen blocker. It is primarily used for treating breast cancer in women who have reached menopause. The mechanism of action involves regulation of estrogen levels in the body, which in turn helps to slow down the growth of cancerous cells.

It is essential to follow your doctor's advice regarding the dosage and frequency of the injections. The appropriate amount of medication required for symptom improvement will be determined by your doctor. It is important to adhere to the prescribed treatment duration.

Like any medication, Celvestrant PFS Injection may cause some side effects. The most commonly reported side effects include reactions at the injection site, headaches, vomiting, allergic reactions, and nausea. If you experience any of these side effects and find them bothersome or severe, it is important to inform your doctor promptly. Your healthcare provider may be able to suggest strategies to manage or prevent these side effects.

Prior to initiating treatment with Celvestrant PFS Injection, it is crucial to inform your doctor about any history of kidney or liver disease, bleeding disorders, or previous use of blood clotting medications.
